Abstract : The velocity corrected effective stiffness or microstructure plate theory is utilized to study the flexural vibrations if simply supported rectangular plates and comparisons are made to an effective modulus plate theory. In each case frequency equations for simply supported edges are developed by passing solutions harmonic in both length and width through the differential equations while automati-cally satisfying the conditions for simple supports. Careful consid-eration is given to the variations of dimensionless frequency with such dimensionless parameters as width-to- thickness ratio, number of layer pairs, density ratio, thickness ratio, width-to- length ratio, and elastic ratio and such results are discussed graphically.
